Does anyone know Haier, Sun Rain, Tsinghua Sunshine, Linuo Rite, Huangming s balcony style too

Hehe, it's all the same. The angle is not brand-related.

The basis for determination is that according to the latitude of the installation site, the angle between the vertical plane or the horizontal plane is actually the same thing, the relationship between 90 °;

If the latitude of the installation site is 30°, then the best angle to the vertical plane is 60°, which can be plus or minus 10°.

According to the computer simulation software, when the inclination angle of the collector is approximately the local latitude, the maximum annual solar irradiation can be obtained. For more full access to solar energy, the inclination angle should be in the range of 10°.

The best amount of solar irradiation should be obtained in winter, which should be 10° greater than the local latitude and 10° smaller in summer.

The arrangement of collectors on the balcony should consider the blocking between buildings, and it is best to simulate it with sunshine simulation software to ensure that its daily sunshine hours are greater than 4h.

Normal is between 38-50 degrees. According to the different latitudes and angles of various places, Guangdong, Guangxi and other places are 38 degrees to 42 degrees; It is generally 42-50 degrees to Beijing in the north, and 50 degrees in the northeast, northwest and other places.
